Test Observability – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
The practice of collecting and analyzing detailed data about test executions to understand test behavior, root-cause failures and improve test suites.
In simple words
Rich telemetry from your test runs (timings, flake rate, root causes) so you can improve the suite over time.
Exam tip
Distinct from application observability — this is about the tests themselves.
